In the Linux kernel, the following vulnerability has been resolved:

media: saa7164: add ioremap return checks and cleanups

Add checks for ioremap return values in saa7164 dev setup(). If ioremap for BAR0 or BAR2 fails, release the already allocated PCI memory regions, remove the device from the global list, decrement the device count, and return -ENODEV.

This prevents potential null pointer dereferences and ensures proper cleanup on memory mapping failures.
